Dele Alli was in a confident mood after his double helped Tottenham thump Watford 4-1, but hopes his wait for a first Spurs hat-trick ends soon.
The England midfielder has five goals in his last three games after following up his double in the win over Southampton - which was also 4-1 - with another at Vicarage Road.
"Yeah, definitely [understood]," he told Sky Sports when asked about his substitution.
"Obviously everyone wants to be getting goals and after the last game as well - when I got two and didn't get my hat-trick - I was kicking myself a bit.
"I wanted to get it, but the most important thing is the result.
"It is good for my confidence. It is always nice to help the team, whether that is scoring goals or setting them up.
"It was a solid performance from us. After we got that first goal it was a pretty comfortable win in the end.
"Everyone put a good shift in and it gives us a lot of confidence going into the next game."
He said: "It is massive. We know that, everyone knows that.
"It's going to be a fantastic atmosphere coming to our place. We are looking forward to it. We just need to recover now and get ready for the game.
"We just need to go out there and beat Chelsea and stop their form - then hopefully they will drop a few more points."
